DETAILED DESCRIPTION

The invention will now be described more fully hereinafter with reference to the accompanying drawings, in which various embodiments of the invention are shown. This invention may, however, be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will filly convey the scope of the invention to those skilled in the art.

It will also be understood that when a layer is referred to as being “on” another layer or substrate, it can be directly on the other layer or substrate, or intervening layers may also be present. The same reference numbers indicate the same components throughout the specification.

It will be understood that, although the terms “first,” “second,” etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another element. For instance, a first element discussed below could be termed a second element without departing from the teachings of the invention. Similarly, the second element could also be termed the first element.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used herein, “a”, “an,” “the,” and “at least one” do not denote a limitation of quantity, and are intended to include both the singular and plural, unless the context clearly indicates otherwise. For example, “an element” has the same meaning as “at least one element,” unless the context clearly indicates otherwise. “At least one” is not to be construed as limiting “a” or “an.” “Or” means “and/or.” As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items. It will be further understood that the terms “comprises” and/or “comprising,” or “includes” and/or “including” when used in this specification, specify the presence of stated features, regions, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, regions, integers, steps, operations, elements, components, and/or groups thereof.

Furthermore, relative terms, such as “lower” or “bottom” and “upper” or “top,” may be used herein to describe one element's relationship to another element as illustrated in the Figures. It will be understood that relative terms are intended to encompass different orientations of the device in addition to the orientation depicted in the Figures. For example, if the device in one of the figures is turned over, elements described as being on the “lower” side of other elements would then be oriented on “upper” sides of the other elements. The term “lower,” can therefore, encompasses both an orientation of “lower” and “upper,” depending on the particular orientation of the figure. Similarly, if the device in one of the figures is turned over, elements described as “below” or “beneath” other elements would then be oriented “above” the other elements. The terms “below” or “beneath” can, therefore, encompass both an orientation of above and below.

Each of the features of the various embodiments of the disclosure may be combined or combined with each other, in part or in whole, and technically various interlocking and driving are possible. Each embodiment may be implemented independently of each other or may be implemented together in an association.

Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the disclosure, and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

Embodiments are described herein with reference to cross section illustrations that are schematic illustrations of idealized embodiments. As such, variations from the shapes of the illustrations as a result, for example, of manufacturing techniques and/or tolerances, are to be expected. Thus, embodiments described herein should not be construed as limited to the particular shapes of regions as illustrated herein but are to include deviations in shapes that result, for example, from manufacturing. For example, a region illustrated or described as flat may, typically, have rough and/or nonlinear features. Moreover, sharp angles that are illustrated may be rounded. Thus, the regions illustrated in the figures are schematic in nature and their shapes are not intended to illustrate the precise shape of a region and are not intended to limit the scope of the claims.

Hereinafter, embodiments of the invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a plan view illustrating a display device according to an embodiment.

Referring to FIG. 1 , a display device 10 is a device that displays a moving image or a still image, and may be used as or define a display screen of each of various products such as televisions, laptop computers, monitors, billboards, and Internet of Things (“IOT”) devices as well as portable electronic devices such as mobile phones, smartphones, tablet personal computers (“PC”s), smart watches, watch phones, mobile communication terminals, electronic notebooks, electronic books, portable multimedia players (“PMP”s), navigation devices, and ultra mobile PCs (“UMPC”s).

An embodiment of the display device 10 may be a light emitting display device such as an organic light emitting display device using an organic light emitting diode, a quantum dot light emitting display device including a quantum dot light emitting layer, an inorganic light emitting display device including an inorganic semiconductor, or a micro light emitting display device using a micro or nano light emitting diode (micro LED or nano LED). Hereinafter, for convenience of description, embodiments where the display device 10 is the organic light emitting display device will be described in detail, but the disclosure is not limited thereto.

In an embodiment, the display device 10 includes a display panel 100, a display driving circuit 200, and a circuit board 300.

The display panel 100 may be in a rectangular shape, in a plan view, having short sides in a first direction DR1 and long sides in a second direction DR2 crossing the first direction DR1. A corner where the short side in the first direction DR1 and the long side in the second direction DR2 meet may be right-angled or rounded with a predetermined curvature. The shape of the display panel 100 in a plan view is not limited to the rectangular shape, and may be a polygonal shape, a circular shape, or an elliptical shape. The display panel 100 may be flat, but is not limited thereto. In an embodiment, for example, the display panel 100 may include curved surface parts formed at left and right distal ends thereof and having a constant curvature or a variable curvature. In an embodiment, the display panel 100 may be flexible or flexibly formed to be bent, folded, or rolled.

The display panel 100 may include a display area DA that displays an image and a non-display area NDA that does not display an image.

The display area DA may include display pixels SPX (see FIG. 2 ) that display the image. The display area DA may occupy most of an area of the display panel 100. The display area DA may be disposed at a center of the display panel 100.

The non-display area NDA may be disposed adjacent to the display area DA. The non-display area NDA may be disposed to surround the display area DA. The non-display area NDA may be an edge area of the display panel 100.

The non-display area NDA may include a first dummy area DMA1, a second dummy area DMA2, a first scan driver SDC1, a second scan driver SDC2, and a pad area PDA.

The first dummy area DMA1 may be disposed on one side (e.g., the left side) of the display area DA, and the second dummy area DMA2 may be disposed on another side (e.g., an opposing side or the right side) of the display area DA. The first dummy area DMA1 and the second dummy area DMA2 may be areas defined or designed in consideration of a deposition quality of display emission layers of display pixels SPX (see FIG. 2 ) disposed at edges of a fine metal mask when the display emission layers of the display pixels SPX (see FIG. 2 ) of the display area DA are formed using the fine metal mask. Therefore, dummy emission layers DEL including substantially a same material as the display emission layers of the display pixels SPX (see FIG. 2 ) may be disposed in the first dummy area DMA1 and the second dummy area DMA2.

The first scan driver SDC1 may be disposed adjacent to the first dummy area DMA1. In an embodiment, for example, the first scan driver SDC1 may be disposed on the left side of the first dummy area DMA1.

The second scan driver SDC2 may be disposed adjacent to the second dummy area DMA2. In an embodiment, for example, the second scan driver SDC2 may be disposed on the right side of the second dummy area DMA2.

Each of the first scan driver SDC1 and the second scan driver SDC2 may include a scan signal output unit connected to scan lines of the display area DA. The scan lines may include scan write lines GWLk (see FIG. 2 ) and scan initialization lines GILk (see FIG. 2 ). Each of the first scan driver SDC1 and the second scan driver SDC2 may further include an emission signal output unit connected to emission lines EMLk (see FIG. 2 ) of the display area DA.

The first scan driver SDC1 may be connected to display pads PD of the pad area PDA through first scan control lines GCL1. The second scan driver SDC2 may be connected to the display pads PD of the pad area PDA through second scan control lines GCL2. Accordingly, each of the first scan driver SDC1 and the second scan driver SDC2 may be electrically connected to the display driving circuit 200 through the display pads PD of the pad area PDA and the circuit board 300.

The scan signal output unit of each of the first scan driver SDC1 and the second scan driver SDC2 may receive scan control signals from the display driving circuit 200, generate scan signals based on the scan control signals, and output the scan signals to the scan lines. In addition, the emission signal output unit of each of the first scan driver SDC1 and the second scan driver SDC2 may receive emission control signals from the display driving circuit 200, generate emission signals based on the emission control signals, and output the emission signals to the emission lines.

A first power line VSL may be disposed in the non-display area NDA. The first power line VSL may be disposed to surround the display area DA. The first power line VSL may be disposed on the lower side and the upper side of the display area DA, in the first dummy area DMA1, and in the second dummy area DMA2. The first power line VSL may be connected to the display pads PD of the pad area PDA. That is, the first power line VSL may be electrically connected to the circuit board 300 through the display pads PD of the pad area PDA. Therefore, the first power line VSL may receive a first power voltage from the circuit board 300.

First power connection lines VSCL may be disposed in the display area DA, the first dummy area DMA1, and the second dummy area DMA2. The first power connection lines VSCL may extend in the first direction DR1. The first power connection lines VSCL may be connected to the first power line VSL in each of the first dummy area DMA1 and the second dummy area DMA2. Accordingly, the first power voltage of the first power line VSL may be supplied to the first power connection lines VSCL.

The pad area PDA may be disposed on one side (e.g., the lower side) of the display panel 100. The pad area PDA may include a plurality of display pads PD.

The display driving circuit 200 may generate signals and voltages for driving the display panel 100. The display driving circuit 200 may be formed as an integrated circuit (“IC”) and attached onto the circuit board 300 in a chip on film (“COF”) manner.

The circuit board 300 may be attached to the pad area PDA disposed at one end of the display panel 100. Accordingly, the circuit board 300 may be electrically connected to the display panel 100. The display panel 100 may receive power voltages through the circuit board 300, and may receive the scan control signals and data voltages of the display driving circuit 200. The circuit board 300 may be a flexible film such as a chip on film.

In an embodiment, as illustrated in FIG. 1 , the first power line VSL is not disposed at edges of the display panel 100, but may be disposed in the first dummy area DMA1 and the second dummy area DMA2 in which the dummy emission layers DEL are disposed. Therefore, in such an embodiment, first power lines disposed on the left side of the first scan driver SDC1 and on the right side of the second scan driver SDC2 may be omitted, and thus, a width of the non-display area may be decreased.

FIG. 2 is a circuit diagram illustrating a display pixel of a display area according to an embodiment.

Referring to FIG. 2 , an embodiment of the display pixel SPX may be connected to a k-th (k is a positive integer) scan initialization line GILk, a k-th scan write line GWLk, and a k-th emission line EMLk.

When the display device 10 is contracted as illustrated in FIG. 7 , the second connection pattern CNP2 may be bent in a third direction DR3. When the display device 10 is stretched as illustrated in FIG. 8 , the second connection pattern CNP2 may be unbent. Therefore, a length of the second connection pattern CNP2 in the first direction DR1 when the display device 10 is stretched in the first direction DR1 may be greater than that when the display device 10 is contracted.

Similarly, when the display device 10 is contracted, each of the first and third to eighth connection patterns CNP1 and CNP3 to CNP8 may be bent in the third direction DR3. When the display device 10 is stretched, each of the first and third to eighth connection patterns CNP1 and CNP3 to CNP8 may be unbent. Therefore, a length of the third connection pattern CNP3 in the second direction DR2, a length of the fourth connection pattern CNP4 in the second direction DR2, a length of the fifth connection pattern CNP5 in the second direction DR2, and a length of the sixth connection pattern CNP6 in the second direction DR2 when the display device 10 is stretched in the second direction DR2 may be greater than those when the display device 10 is contracted.

In addition, the first power connection line VSCL may extend in a zigzag or winding form along the first direction DR1 in the display area DA and be connected to the first power line VSL in each of the first dummy area DMA1 and the second dummy area DMA2.

The first light emitting unit ELU1, the second light emitting unit ELU2, and the third light emitting unit ELU3 may be arranged in the first direction DR1. The first light emitting unit ELU1 may be disposed on one side of the second light emitting unit ELU2, and the third light emitting unit ELU3 may be disposed on another side (or an opposing side) of the second light emitting unit ELU2. An area of the second light emitting unit ELU2 may be greater than an area of the first light emitting unit ELU1 and an area of the third light emitting unit ELU3.

The first pixel electrode PXE1 of the first light emitting unit ELU1, the second pixel electrode PXE2 of the second light emitting unit ELU2, and the third pixel electrode PXE3 of the third light emitting unit ELU3 may be arranged in the first direction DR1. The first pixel electrode PXE1 may be disposed on one side of the second pixel electrode PXE2, and the third pixel electrode PXE3 may be disposed on another side (or an opposing side) of the second pixel electrode PXE2. An area of the second pixel electrode PXE2 may be greater than an area of the first pixel electrode PXE1 and an area of the third pixel electrode PXE3. In addition, the area of the first pixel electrode PXE1 may be greater than the area of the first light emitting unit ELU1, the area of the second pixel electrode PXE2 may be greater than the area of the second light emitting unit ELU2, and the area of the third pixel electrode PXE3 may be greater than the area of the third light emitting unit ELU3.

The first pixel electrode PXE1 may be connected to a first pixel driver through a first pixel contact hole PCNT1, and may thus receive a driving voltage of the first pixel driver. The second pixel electrode PXE2 may be connected to a second pixel driver through a second pixel contact hole PCNT2, and may thus receive a driving voltage of the second pixel driver. The third pixel electrode PXE3 may be connected to a third pixel driver through a third pixel contact hole PCNT3, and may thus receive a driving voltage of the third pixel driver.

In an embodiment, as illustrated in FIGS. 4 and 5 , the second pixel electrode PXE2 of the second light emitting unit ELU2 overlaps the scan initialization lines GILk/GILk+1, the scan write lines GWLk/GWLk+1, the emission lines EMLk/EMLk+1, and the first power connection line VSCL and the first pixel electrode PXE1 of the first light emitting unit ELU1, the second pixel electrode PXE2 of the second light emitting unit ELU2, and the third pixel electrode PXE3 of the third light emitting unit ELU3 overlap the red data lines RDLj/RDLj+1/RDLj+2/RDLj+3, the blue data lines BDLj/BDLj+1/BDLj+2/BDLj+3, the green data lines GDLj/GDLj+1/GDLj+2/GDLj+3, and the second power line VDL/VDL+1/VDL+2/VDL+3, but an embodiment of the disclosure is not limited thereto. In an embodiment, at least one selected from the first pixel electrode PXE1 of the first light emitting unit ELU1, the second pixel electrode PXE2 of the second light emitting unit ELU2, and the third pixel electrode PXE3 of the third light emitting unit ELU3 may overlap at least one selected from the scan initialization lines GILk/GILk+1, the scan write lines GWLk/GWLk+1, the emission lines EMLk/EMLk+1, the first power connection line VSCL, the red data lines RDLj/RDLj+1/RDLj+2/RDLj+3, the blue data lines BDLj/BDLj+1/BDLj+2/BDLj+3, the green data lines GDLj/GDLj+1/GDLj+2/GDLj+3, and the second power line VDL/VDL+1/VDL+2/VDL+3.

The island common electrode ICE may be disposed in each of the first to fourth island patterns ISP1, ISP2, ISP3, and ISP4 in the display area DA. In each of the first to fourth island patterns ISP1, ISP2, ISP3, and ISP4, the island common electrode ICE may be connected to a first common connection electrode CCU1 through a first common contact hole CCNT1. In an embodiment, the island common electrode ICE may not be disposed in the first to eighth connection patterns CNP1 to CNP8 to prevent the island common electrode ICE from being damaged according to a change in length of each of the first to eighth connection patterns CNP1 to CNP8.

The first common connection electrode CCU1 may be disposed in each of the first to fourth island patterns ISP1, ISP2, ISP3, and ISP4 in the display area DA. The first common connection electrode CCU1 may be connected to the first power connection line VSCL through a second common contact hole CCNT2. Although not illustrated in FIGS. 4 to 6 , the first power connection line VSCL may overlap the first common connection electrode CCU1 and the second common contact hole CCNT2 in the third direction DR3. Therefore, the first power voltage of the first power line VSL may be supplied to the island common electrode ICE through the first power connection line VSCL and the first common connection electrode CCU1.

The first common connection electrode CCU1 may be disposed in or directly on a same layer as the first pixel electrode PXE1, the second pixel electrode PXE2, and the third pixel electrode PXE3. Therefore, the first common connection electrode CCU1 may not overlap the first pixel electrode PXE1, the second pixel electrode PXE2, and the third pixel electrode PXE3.

In an embodiment, as illustrated in FIGS. 4 to 6 , the first to fourth island patterns ISP1 to ISP4 partitioned by the cutout parts CUP1 to CUP4 may be connected to each other by the first to eighth connection patterns CNP1 to CNP8, and the first to eighth connection patterns CNP1 to CNP8 may be in a bent state when the display device 10 is contracted, but may be in an unbent state when the display device 10 is stretched. Therefore, shapes of the first to fourth island patterns ISP1 to ISP4 do not change and lengths of the first to eighth connection patterns CNP1 to CNP8 change, such that a width of each of the cutout parts CUP1 to CUP4 may be increased or decreased. Accordingly, the display area DA may be effectively stretched and contracted.

FIGS. 9 and 10 are plan views illustrating a first dummy area according to an embodiment in detail. FIG. 11 is a plan view illustrating a first island pattern of FIG. 9 in detail.

In FIG. 9 , island patterns ISP1 to ISP4, connection patterns CNP1 to CNP8, and cutout parts CUP1 to CUP4 of the first dummy area DMA1 when the display device 10 is contracted are illustrated. In FIG. 10 , island patterns ISP1 to ISP4, connection patterns CNP1 to CNP8, and cutout parts CUP1 to CUP4 of the first dummy area DMA1 when the display device 10 is stretched are illustrated.

The island patterns ISP and the connection patterns CNP of the first dummy area DMA1 may be substantially the same as the island patterns ISP and the connection patterns CNP of the display area DA described above with reference to FIGS. 4 to 6 . Therefore, any repetitive detailed description of the island patterns ISP and the connection patterns CNP of the first dummy area DMA1 will be omitted.

Scan initialization lines GILk/GILk+1, scan write lines GWLk/GWLk+1, emission lines EMLk/EMLk+1, a first power connection line VSCL, and a first power line VSL may be disposed in each of first to fourth island patterns ISP1, ISP2, ISP3, and ISP4 in the first dummy area DMA1.

A k-th scan initialization line GILk, a k-th scan write line GWLk, and a k-th emission line EMLk may sequentially pass through the first connection pattern CNP1, the first island pattern ISP1, the second connection pattern CNP2, and the second island pattern ISP2. In addition, a (k+1)-th scan initialization line GIL, a (k+1)-th scan write line GWLk+1, and a (k+1)-th emission line EMLk+1 may sequentially pass through the seventh connection pattern CNP7, the third island pattern ISP3, the eighth connection pattern CNP8, and the fourth island pattern ISP4. That is, in the first dummy area DA, the scan initialization lines GILk/GILk+1, the scan write lines GWLk/GWLk+1, and the emission lines EMLk/EMLk+1 may extend in a zigzag or winding form along the first direction DR1 and be connected to the first scan driver SDC1 and the second scan driver SDC2.

The first power line VSL may sequentially pass through the third connection pattern CNP3, the first island pattern ISP1, the fourth connection pattern CNP4, and the second island pattern ISP2. In addition, the first power line VSL may sequentially pass through the fifth connection pattern CNP5, the second island pattern ISP2, the sixth connection pattern CNP6, and the fourth island pattern ISP4. The first power line VSL may be connected to a second common connection electrode CCU2 through a fourth common contact hole CCNT4 in each of the first to fourth island patterns ISP1, ISP2, ISP3, and ISP4. That is, in the first dummy area DMA1, the first power line VSL may extend in a zigzag or winding form along the second direction DR2.

In each of the first to fourth island patterns ISP1, ISP2, ISP3, and ISP4, the first power connection line VSCL may be branched from the first power line VSL. In the first dummy area DMA1, the first power connection line VSCL may extend in a zigzag or winding form along the first direction DR1.

In an embodiment, for example, as illustrated in FIG. 9 , the first power connection line VSCL branched from the first power line VSL in the first island pattern ISP1 may extend to the second connection pattern CNP2, the second island pattern ISP2, and the first connection pattern CNP1. In such an embodiment, the first power connection line VSCL branched from the first power line VSL in the first island pattern ISP1 and extending to the second island pattern ISP2 may be connected to the first power line VSL in the second island pattern ISP2.

In an embodiment, as illustrated in FIG. 9 , the first power connection line VSCL branched from the first power line VSL in the third island pattern ISP3 may extend to the eighth connection pattern CNP8, the fourth island pattern ISP4, and the seventh connection pattern CNP7. In such an embodiment, the first power connection line VSCL branched from the first power line VSL in the third island pattern ISP3 and extending to the fourth island pattern ISP4 may be connected to the first power line VSL in the fourth island pattern ISP4.

A first dummy emission layer DEL1, a second dummy emission layer DEL2, and a third dummy emission layer DEL3 may be disposed in each of the first to fourth island patterns ISP1, ISP2, ISP3, and ISP4 in the first dummy area DMA1.

The first dummy emission layer DEL1 may include substantially a same material as a first display emission layer EL1 of the first light emitting unit ELU1. The second dummy emission layer DEL2 may include substantially a same material as a second display emission layer of the second light emitting unit ELU2. The third dummy emission layer DEL3 may include substantially a same material as a third display emission layer of the third light emitting unit ELU3.

The first dummy emission layer DEL1, the second dummy emission layer DEL2, and the third dummy emission layer DEL3 may be arranged in the first direction DR1. The first dummy emission layer DEL1 may be disposed on one side of the second dummy emission layer DEL2, and the third dummy emission layer DEL3 may be disposed on another side (or an opposing side) of the second dummy emission layer DEL2. An area of the second dummy emission layer DEL2 may be greater than an area of the first dummy emission layer DEL1 and an area of the third dummy emission layer DEL3.

In an embodiment, as illustrated in FIGS. 9 and 10 , the second dummy emission layer DEL2 overlaps the scan initialization lines GILk/GILk+1, the scan write lines GWLk/GWLk+1, the emission lines EMLk/EMLk+1, and the first power connection line VSCL and the first dummy emission layer DEL1, the second dummy emission layer DEL2, and the third dummy emission layer DEL3 overlap the first power line VSL, but an embodiment of the disclosure is not limited thereto. At least one selected from the first dummy emission layer DEL1, the second dummy emission layer DEL2, and the third dummy emission layer DEL3 may overlap at least one selected from the scan initialization lines GILk/GILk+1, the scan write lines GWLk/GWLk+1, the emission lines EMLk/EMLk+1, the first power connection line VSCL, the red data lines RDLj/RDLj+1/RDLj+2/RDLj+3, the blue data lines BDLj/BDLj+1/BDLj+2/BDLj+3, and the green data lines GDLj/GDLj+1/GDLj+2/GDLj+3.

The second common connection electrode CCU2 may be disposed in each of the first to fourth island patterns ISP1, ISP2, ISP3, and ISP4 in the first dummy area DMA1. In the first dummy area DMA1, a dummy common electrode DCE of each of the first to fourth island patterns ISP1, ISP2, ISP3, and ISP4 may be connected to the second common connection electrode CCU2 through a third common contact hole CCNT3. In the first dummy area DMA1, the second common connection electrode CCU2 of each of the first to fourth island patterns ISP1, ISP2, ISP3, and ISP4 may be connected to the first power line VSL through the fourth common contact hole CCNT4. Although not illustrated in FIGS. 9 to 11 , the first power connection line VSCL may overlap the second common connection electrode CCU2 and the fourth common contact hole CCNT4 in the third direction DR3. Therefore, the first power voltage of the first power line VSL may be supplied to the dummy common electrode DCE through the first power connection line VSCL and the second common connection electrode CCU2.

The second common connection electrode CCU2 may be disposed in or directly on a same layer as the first pixel electrode PXE1, the second pixel electrode PXE2, the third pixel electrode PXE3, and the first common connection electrode CCU1. The second common connection electrode CCU2 may not overlap the first dummy emission layer DEL1, the second dummy emission layer DEL2, and the third dummy emission layer DEL3.

In an embodiment, as illustrated in FIGS. 9 to 11 , in the first dummy area DMA1 as well as the display area DA, shapes of the first to fourth island patterns ISP1 to ISP4 do not change and lengths of the first to eighth connection patterns CNP1 to CNP8 change, such that a width of each of the cutout parts CUP1 to CUP4 may be adjusted. Therefore, the first dummy area DMA1 may be effectively stretched and contracted.

In such an embodiment, as illustrated in FIGS. 9 to 11 , the first power line VSL may overlap the first dummy emission layer DEL1, the second dummy emission layer DEL2, and the third dummy emission layer DEL3 and extend in a zigzag or winding form along the second direction DR2, in the first dummy area DMA1. Since the first power line VSL is not disposed at the edge of the display panel 100, a width of the non-display area NDA may be decreased as compared with a case where the first power line VSL is disposed at the edge of the display panel 100.

In such an embodiment, the second dummy area DMA2 is substantially the same as the first dummy area DMA1 described above with reference to FIGS. 9 to 11 , and thus, any repetitive detailed description of the second dummy area DMA2 will be omitted.

The island patterns ISP and the connection patterns CNP of the first scan driver SDC1 may be substantially the same as the island patterns ISP and the connection patterns CNP of the display area DA described above with reference to FIGS. 4 and 5. Therefore, any repetitive detailed description of the island patterns ISP and the connection patterns CNP of the first scan driver SDC1 will be omitted.

A scan stage circuit unit STC may be disposed in each of the first to fourth island patterns ISP1, ISP2, ISP3, and ISP4 in the first scan driver SDC1.

In an embodiment, as illustrated in FIGS. 12 and 13 , in the first scan driver SDC1 as well as the display area DA and the first dummy area DMA1, shapes of the first to fourth island patterns ISP1 to ISP4 do not change and lengths of the first to eighth connection patterns CNP1 to CNP8 change, such that a width of each of the cutout parts CUP1 to CUP4 may be adjusted. Therefore, the first scan driver SDC1 may be effectively stretched and contracted.

In such an embodiment, the second scan driver SDC2 is substantially the same as the first scan driver SDC1 described with reference to FIGS. 12 and 13 , and thus, any repetitive detailed description of the second scan driver SDC2 will be omitted.

In such an embodiment, the (k−2)-th scan initialization line GILk_2 may be disposed in or directly on a same layer as the first gate electrode G1 of the first thin film transistor TFT1, the second gate electrode G2 of the second thin film transistor TFT2, and the first capacitor electrode CAE1. In addition, the (k−2)-th scan initialization line GILk_2 may include a same material as the first gate electrode G1 of the first thin film transistor TFT1, the second gate electrode G2 of the second thin film transistor TFT2, and the first capacitor electrode CAE1.

The (k−1)-th scan initialization line GILk_1 may be connected to the (k−2)-th scan initialization line GILk_2 through a fourth contact hole CNT4 defined through the first interlayer insulating layer 141 and the second interlayer insulating layer 142 in the first island pattern ISP1. Since the (k−2)-th scan initialization line GILk_2 is disposed on the gate insulating layer 130 and the first power line VSL is disposed on the second interlayer insulating layer 142, the (k−2)-th scan initialization line GILk_2 and the first power line VSL may cross each other. Since the space of the first island pattern ISP1 is wider than the space of the first connection pattern CNP1, a width of the (k−2)-th scan initialization line GILk_2 may be greater than a width of the (k−1)-th scan initialization line GILk_1.

In such an embodiment, each of the stage connection lines STCL1 and STCL2 may be formed to be substantially the same as the first power connection line VSCL, the k-th emission line EMLk, the k-th scan write line GWLk, and the k-scan initialization line GILk described in connection with FIGS. 17 and 18 .

The first sub-power connection line VSCL1 may be connected to the third sub-power connection line VSCL3 through a fifth contact hole CNT5 defined through the second interlayer insulating layer 142 in the first island pattern ISP1. Since the third sub-power connection line VSCL3 is disposed on first interlayer insulating layer 141 and the first power line VSL is disposed on the second interlayer insulating layer 142, the third sub-power connection line VSCL3 and the first power line VSL may cross each other.

Since the space of the first island pattern ISP1 is wider than the space of the first connection pattern CNP1, a width of the third sub-power connection line VSCL3 may be greater than a width of the first sub-power connection line VSCL1. In addition, since the space of the first island pattern ISP1 is wider than the space of the first connection pattern CNP1, the first sub-power connection line VSCL1 may be divided into two lines, that is, the second sub-power connection line VSCL2 and the third sub-power connection line VSCL3, and such two lines may cross the first power line VSL, in the first island pattern ISP1.

In addition, since the space of the first island pattern ISP1 is wider than the space of the first connection pattern CNP1, the (k−1)-th emission line EMLk_1 may be divided into two lines, that is, the (k−2)-th emission line EMLk_2 and the (k−3)-th emission line EMLk_3 and such two lines may cross the first power line VSL, in the first island pattern ISP1. Accordingly, resistance of the k-th emission line EMLk may be decreased.

The (k−1)-th scan write line GWLk_1 may be connected to the (k−3)-th scan write line GWLk_3 through a seventh contact hole CNT7 defined through the second interlayer insulating layer 142 in the first island pattern ISP1. Since the (k−3)-th scan write line GWLk_3 is disposed on the first interlayer insulating layer 141 and the first power line VSL is disposed on the second interlayer insulating layer 142, the (k−3)-th scan write line GWLk_3 and the first power line VSL may cross each other.

Since the space of the first island pattern ISP1 is wider than the space of the first connection pattern CNP1, a width of the (k−3)-th scan write line GWLk_3 may be greater than a width of the (k−1)-th scan write line GWLk_1. In addition, since the space of the first island pattern ISP1 is wider than the space of the first connection pattern CNP1, the (k−1)-th scan write line GWLk_1 may be divided into two lines, that is, the (k−2)-th scan write line GWLk_2 and the (k−3)-th scan write line GWLk_3 and such two lines may cross the first power line VSL, in the first island pattern ISP1. Accordingly, resistance of the k-th scan write line GWLk may be decreased.

The (k−1)-th scan initialization line GILk_1 may be connected to the (k−3)-th scan initialization line GILk_3 through an eighth contact hole CNT8 defined through the second interlayer insulating layer 142 in the first island pattern ISP1. Since the (k−3)-th scan initialization line GILk_3 is disposed on the first interlayer insulating layer 141 and the first power line VSL is disposed on the second interlayer insulating layer 142, the (k−3)-th scan initialization line GILk_3 and the first power line VSL may cross each other.

Since the space of the first island pattern ISP1 is wider than the space of the first connection pattern CNP1, a width of the (k−3)-th scan initialization line GILk_3 may be greater than a width of the (k−1)-th scan initialization line GILk_1. In addition, since the space of the first island pattern ISP1 is wider than the space of the first connection pattern CNP1, the (k−1)-th scan initialization line GILk_1 may be divided into two lines, that is, the (k−2)-th scan initialization line GILk_2 and the (k−3)-th scan initialization line GILk_3 and such two lines may cross the first power line VSL, in the first island pattern ISP1. Accordingly, resistance of the k-th scan initialization line GILk may be decreased.

In such an embodiment, each of the stage connection lines STCL1 and STCL2 may be formed to be substantially the same as the first power connection line VSCL, the k-th emission line EMLk, the k-th scan write line GWLk, and the k-scan initialization line GILk described in connection with FIGS. 19 and 20 .

FIG. 21 is a plan view illustrating a first island pattern of a first dummy area according to an alternative embodiment in detail. FIG. 22 is a cross-sectional view illustrating an embodiment of a display panel taken along line F-F′ of FIG. 21 .

An embodiment of FIGS. 21 and 22 is substantially the same as the embodiment of FIGS. 11 and 15 except that in the first dummy area DMA1, the first power line VSL includes a first sub-power line VSL1 and a second sub-power line VSL2.

Referring to FIGS. 21 and 22 , the first sub-power line VSL1 may be disposed on the second interlayer insulating layer 142. In such an embodiment, the first sub-power line VSL1 may be disposed in or directly on a same layer as the first anode connection electrode ANDE1, the data lines RDLj, BDLj, and GDLj, the first power line VSL, and the first power connection line VSCL. In addition, the first sub-power line VSL1 may include a same material as the first anode connection electrode ANDE1, the data lines RDLj, BDLj, and GDLj, the first power line VSL, and the first power connection line VSCL.

The second sub-power line VSL2 may be disposed on the first planarization layer 160.

In an embodiment, as illustrated in FIGS. 21 and 22 , the second sub-power line VSL2 is disposed in the first island pattern ISP1, the first connection pattern CNP1, and the second connection pattern CNP2, but an embodiment of the disclosure is not limited thereto. In an alternative embodiment, for example, in the first connection pattern CNP1 and the second connection pattern CNP2, the second sub-power line VSL2 is disposed on a surface other than a neutral plane, and thus, a crack may occur in the second sub-power line VSL2 when the first connection pattern CNP1 and the second connection pattern CNP2 are bent. Therefore, the second sub-power line VSL2 may be disposed on the first island pattern ISP1 of which a change in shape does not exist or is minimized even though the display device 10 is contracted and stretched, and may not be disposed on the first connection pattern CNP1 and the second connection pattern CNP2.

In an embodiment, as illustrated in FIGS. 21 and 22 , the first power line VSL includes the first sub-power line VSL1 and the second sub-power line VSL2 overlapping each other in the third direction DR3, such that an area of the first power line VSL may be increased as a compared with a length of the first power line VSL, and thus, resistance of the first power line VSL may be decreased.

In such an embodiment, a first power line VSL of the second dummy area DMA2 may be substantially the same as the first power line VSL illustrated in FIGS. 21 and 22 , and thus, any repetitive detailed description of the first power line VSL of the second dummy area DMA2 will be omitted.

FIG. 23 is a plan view illustrating a first island pattern of a first dummy area according to an alternative embodiment in detail. FIG. 24 is a cross-sectional view illustrating an embodiment of a display panel taken along line G-G′ of FIG. 23 .

Still another embodiment of FIGS. 23 and 24 is different from another embodiment of FIGS. 21 and 22 in that in the first dummy area DMA1, the first power line VSL further includes a third sub-power line VSL3.

Referring to FIGS. 23 and 24 , the third sub-power line VSL3 may be disposed on the second planarization layer 180.

The third sub-power line VSL3 may be connected to the second sub-power line VSL2 through a second power contact hole VCNT2 defined through the second planarization layer 180 in the first island pattern ISP1. The third planarization layer 181 may be formed as or defined by an organic film including or made of an acryl resin, an epoxy resin, a phenolic resin, a polyamide resin, a polyimide resin, or the like.

In such an embodiment, the first light emitting element LEL1, the first common connection electrode CCU1, the second common connection electrode CCU2, and the bank 190 illustrated in FIG. 14 may be disposed on the third planarization layer 181. In addition, a third anode connection electrode may be disposed on the second planarization layer 180, and may be connected to the second anode connection electrode through a third connection contact hole defined through the second planarization layer 180. In addition, the first pixel electrode PXE1 of the first light emitting element LEL1 may be connected to the third anode connection electrode through a fourth connection contact hole defined through the third planarization layer 181.

In an embodiment, as illustrated in FIGS. 23 and 24 , the second sub-power line VSL2 and the third sub-power line VSL3 are disposed in the first island pattern ISP1, the first connection pattern CNP1, and the second connection pattern CNP2, but an embodiment of the disclosure is not limited thereto. In the first connection pattern CNP1 and the second connection pattern CNP2, the second sub-power line VSL2 and the third sub-power line VSL3 are disposed on a surface other than a neutral plane, and thus, cracks may occur in the second sub-power line VSL2 and the third sub-power line VSL3 when the first connection pattern CNP1 and the second connection pattern CNP2 are bent. Therefore, the second sub-power line VSL2 and the third sub-power line VSL3 may be disposed on the first island pattern ISP1 of which a change in length is minimized even though the display device 10 is contracted and stretched, and may not be disposed on the first connection pattern CNP1 and the second connection pattern CNP2.

In an embodiment, as illustrated in FIGS. 23 and 24 , the first power line VSL includes the first sub-power line VSL1, the second sub-power line VSL2, and the third sub-power line VSL3 overlapping each other in the third direction DR3, such that an area of the first power line VSL may be increased as a compared with a length of the first power line VSL, and thus, resistance of the first power line VSL may be decreased.

In such an embodiment, a first power line VSL of the second dummy area DMA2 may be substantially the same as the first power line VSL illustrated in FIGS. 23 and 24 , and thus, any repetitive detailed description of the first power line VSL of the second dummy area DMA2 will be omitted.

FIG. 25 is a plan view illustrating a display area according to an alternative embodiment in detail. FIG. 26 is a plan view illustrating a first dummy area according to an alternative embodiment in detail. FIG. 27 is a plan view illustrating a first scan driver according to an alternative embodiment in detail.

In FIG. 25 , island patterns ISP1 to ISP4, connection patterns CNP1 to CNP8, and cutout parts CUP1 to CUP4 of the display area DA when the display device 10 is stretched are illustrated. In FIG. 26 , island patterns ISP1 to ISP4, connection patterns CNP1 to CNP8, and cutout parts CUP1 to CUP4 of the first dummy area DMA1 when the display device 10 is stretched are illustrated. In FIG. 27 , island patterns ISP1 to ISP4, connection patterns CNP1 to CNP8, and cutout parts CUP1 to CUP4 of the first scan driver SDC1 when the display device 10 is stretched are illustrated.

An embodiment of FIGS. 25 to 27 is substantially the same as the embodiment of FIGS. 5, 10, and 13 except that when the display device 10 is contracted and stretched, the first to eighth connection patterns CNP1 to CNP8 are not bent or unbent, and the cutout parts CUP1 to CUP4 become wide. The same or like elements shown in FIGS. 25 to 27 have been labeled with the same reference characters as used above to describe the embodiment shown in FIGS. 5, 10, and 13 , and any repetitive detailed description thereof will hereinafter be omitted or simplified.

Referring to FIGS. 25 to 27 , a width of the first cutout part CUP1 in the first direction DR1 when the display device 10 is stretched may be greater than that when the display device 10 is contracted. The width of the first cutout part CUP1 when the display device 10 is stretched may become greater toward the center of the first cutout part CUP1. That is, a width of the center of the first cutout part CUP1 when the display device 10 is stretched may be greater than a width of an edge of the first cutout part CUP1.

A width of the second cutout part CUP2 in the second direction DR2 when the display device 10 is stretched may be greater than that when the display device 10 is contracted. The width of the second cutout part CUP2 when the display device 10 is stretched may become greater toward the center of the second cutout part CUP2. That is, a width of the center of the second cutout part CUP2 when the display device 10 is stretched may be greater than a width of an edge of the second cutout part CUP2.

A width of the third cutout part CUP3 in the first direction DR1 when the display device 10 is stretched may be greater than that when the display device 10 is contracted. The width of the third cutout part CUP3 when the display device 10 is stretched may become greater toward the center of the third cutout part CUP3. That is, a width of the center of the third cutout part CUP3 when the display device 10 is stretched may be greater than a width of an edge of the third cutout part CUP3.

A width of the fourth cutout part CUP4 in the first direction DR1 when the display device 10 is stretched may be greater than that when the display device 10 is contracted. The width of the fourth cutout part CUP4 when the display device 10 is stretched may become greater toward the center of the fourth cutout part CUP4. That is, a width of the center of the fourth cutout part CUP4 when the display device 10 is stretched may be greater than a width of an edge of the fourth cutout part CUP4.

Since at least portions of the thin film transistor layer TFTL are removed by a laser in the cutout parts CUP1 to CUP4, stretchability of the cutout parts CUP may be higher than that of the connection patterns CNP. Shapes of the island patterns ISP and the connection patterns CNP do not change, and the first cutout part CUP1, the second cutout part CUP2, the third cutout part CUP3, and the fourth cutout part CUP4 may become wide.

In an embodiment, as illustrated in FIGS. 25 to 27 , the first to fourth island patterns ISP1 to ISP4 partitioned by the cutout parts CUP1 to CUP4 are connected to each other by the first to eighth connection patterns CNP1 to CNP8, and thus, the widths of the cutout parts CUP1 to CUP4 when the display device 10 is stretched may be greater than those when the display device 10 is contracted. Therefore, shapes of the first to fourth island patterns ISP1 to ISP4 and the first to eighth connection patterns CNP1 to CNP8 do not change and the width of each of the cutout parts CUP1 to CUP4 may be increased or decreased. Accordingly, the display area DA may be stretched and contracted.
